HEATER.

Application led- September To all whom t may concern.'

Be it known that I, VnLBoRN CLAY GAR- NnR, a subject of the King of Great Britain, a resident of the city of Edmonton, Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Heaters'.y of which the following is a specification.

his invention relates to improvements in heaters designed for use on cookers, water-heaters and other similar appliances, and they objects'of the invention are to so construct the heater that the heat will be stored in a retaining and storage member, and properly applied to the object or arto arrange the several so that there will be a minimum of loss either by conduction, radiation or convection, and to permit of the several parts being readily accessible for inspection.

Further objects are to so construct the heat retaining member ofthe heater to inclose an electrical resistance, and prevent currents of air-passing across the same, the resistance being toall practical purposes hermetically sealed or inclosed, and generally to adapt the several parts to better perform the functions required of them.

With the above and other objects in view the invention consists'essentially of the improved construction and arrangement of parts particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a perspective view of proved heater.

Fig. 2 is a vertical section of the same.

Fig. 3 is a plan view of the heater having the top section of the heat retaining and storage member removed to show the electrical resistance.

Fig. 4 is a plan view of the top portion of the heat retaining and storage member.

Like characters of reference refer to like parts in the several figures.

The resistance element used in the invention is of the type shown in my co-pending application No. 412,803.

Referring to the drawings; A represents my improved heater comprising a casing 10, which is formed of suitable material and is provided intermediate of its height with a transversely extending wall 11 provided my im- Specicaton of Letters Patent.

Patented Nov. 8, 1921. Serial No. 412,802.

witha depending flange 12,

scoured to the casings by Above the wall 11, a sheet of heat non- -fonducting material 13 is positioned, and above this sheet a ring 14 also of heat nonconducting material is located. i block of heat non-conducting material is now placed on the ring 14 so that a dead air compartment 16 is formed in the bodv of the heater. u

The upper wall of the block 15 is formed with a recess 16 in which a heat storage and retaining member 17 fits. i

:L cover 18 is provided having a curled outer edge 19 which embraces the upper edge of the casing 10 and this cover is -formed with a recess 2O and the inner edge 21 overhangs the periphery of the heat retaining and storage member 17.

The heat retaining and storage member hasl an upper section 22, and between the member 17 andthe member 22 an electrical resistance 23 is positioned and inclosed. Posts 21 and 25 are connected to the electrical resistance 23 and the post 241 is connected with a switch 26 while the post 25 is connected to a socket 27. The socket -27 is then connected by a wire 28 to the switch 26.

VIn the recess 20 a. strip of packing 29 is located and a cover of any suitable material may be placed over the heater to rest on the strip of packing 29, the lower edge of the cover being embraced by the recess 20.

The bottom of the heater is closed by a wall 30 having an annular iiange 31 which embraces the lower end of the a dead air compartment 32 is thus formed in the body of the heater. It will be evident that two dead air compartments are provided which will prevent any loss of heat by radiation, and by the use of the non-conducting members 13, 14 and 15, loss of heat by convection will be eliminated.

lVhen the heater is in use, the socket 27 may be connected by suitable wiring to an ordinary light socket commonly found in household lighting installation, and the switch 26 is then turned on, so that current flows through the resistance 23 and heats the same.

The heat from the resistance is absorbed and stored within the heat retaining and storage members 17 and 22. Any article to be heated may be placed upon the storage member 22.

The heater is of an extremely simple which may be any suitable means.

casing 10, and

nature and the parts are so Varranged that they are not liable to go out of repair, andY the Wiring in the lower compartment of the heater is readily `accessible for inspection, While the resistance can also be quickly inspected by removing the member 22.

As manyV changes could be made in the Vabove construction andV many widely different embodiments of my invention Within the scope ofthe claims, constructed Without departing from the spirit or scope thereof, it

Vis intended that allmatter contained in the Y accompanying speciication` and drawings shall be interpreted as illustrative and not in a limiting sense;

`What l claim as my invention is:

l. A heater of the character described comprising a casinghaving a Wall inter-V mediate of itsV height, a ring of heat retaining material above thevvall, and a block of Vheat non-conducting material above the ring heat non-conducting material above the ring to therebyprovidean air space at the center ofthe ring above the wall, an electric heating means above the block, and asecond block above the electric heating means.

comprising a easing having a Wall intermediate of its height, aringv of heat retainingmaterial above theV Wall, and a block of heat non-conducting material above the ring to thereby provide an air space at the center Y,

of the ring above the vvall, an electric heatingv means above they block, a. second block a ring of heat retainabove the electric heating means, and a cover embracing the said second block.

4. A heater of the character described comprising a. casing having a Wall intermediate o its height, a ring of heat retaining material above the Wall, and. a block. of heat'non-conducting material above the ring to. thereby provideanair space at the center of the ring above the Wall, an electric heating means above. the block, a secondblock and'. through the wall, an electric resistance element, connected. electrically to the upper ends of the/posts.` Y Y i v e 6'. A heater of `the' character described comprising v a, casing having a vvall intermediate 0i' its height, a ring of heat insulatingmaterial above the; Wall, a plurality of blocks above the ring,l connectingV and .con-

ducting posts extendng through the blocks and through the Wall, an electric resistance element connected electrically tothe upper ends or the posts, and a heat retaining member extending above the resistance element. l 3. A heater of the character described ln Witnessk whereof I1 have hereunto set my handn thepresence of tivo-Witnesses.
